Degree:

ICSE Class 8 Chemistry is a subject that helps you understand the working of the worldaround us through atoms and chemical compounds. It also introduces you to chemicalreactions and how to balance them. It is a crucial subject for higher classes and exams. It contains topics such as Language of Chemistry, Atomic structure etc which will help the students in upcoming academic years and classes.

• Learning Objectives:

  UNIT 1: Matter

  UNIT 2: Physical and Chemical Changes

  UNIT 3: Elements, Compounds and Mixtures

  UNIT 4: Atomic Structure

  UNIT 5: Language of Chemistry

  UNIT 6: Chemical Reactions

  UNIT 7: Hydrogen

  UNIT 8: Water

  UNIT 9: Carbon and its compounds

   

• Course Outline:

  UNIT 1: Matter

  • Main postulates of the kinetic molecular theory of matter.
  • Explanation of the change of state of matter on the basis of inter-particle space and interparticle attraction and collision.
  • Law of conservation of mass. (Statement and explanation with examples).

   

  UNIT 2: Physical and Chemical Changes

  • Revise and review the topic on the Physical and Chemical Changes taught in the earlier classes.
  • Physical and Chemical changes – Its classification with examples.

   

  UNIT3: Elements, Compounds and Mixtures

  • Revision of the Elements, Compounds and Mixtures taught in earlier classes.
  • Elements, compounds and mixtures – a brief explanation.
  • Separation of the components of a mixture.
  • Emphasis on the principle of separation.

   

  UNIT 4: Atomic Structure

  • Fundamental subatomic particles present in an atom: the electrons, protons, and neutrons.
  • Nucleus and the extranuclear parts.
  • Atomic number and mass number.

   

  UNIT 5: Language of Chemistry

  • Symbols of the elements.
  • Formulae of the compounds.
  • Chemical equations (from the word equations).
  • Law of conservation of mass.
  • Balancing simple equations
  • Relate the law to the balancing of simple equations.
  • Information gathered from the chemical equations.
  • Limitations of the chemical equation: Catalysts, conditions for reaction, state of the reactants and products, and nature of chemical reaction are not gathered from the given equation.

   

  UNIT 6: Chemical Reactions

  • Types of reactions:
    • Combination
    • Decomposition
    • Displacement
    • Double displacement.
  • Reactivity series:
    • In the reactivity series, metals are arranged in accordance with their reactivities.
    • The metal that displaces the metal ion from a solution is more reactive.
  • Predict the reactivity of metals.
  • Endothermic and exothermic processes/reactions.
  • Neutralisation reaction.
  • Decomposition reactions to form Oxides.
  • Classification of oxides:
    • Acidic
    • Basic
    • Amphoteric
    • Neutral

  Metal oxides are basic; nonmetal oxides are acidic in nature.

  Acidic oxides react with base, and basic oxides react with acids. Some oxides, such as ZnO and PbO react with both acids and bases. These are amphoteric oxides.

   

  UNIT 7: Hydrogen

  • Preparation of the hydrogen from water – electrolysis (Introduction to the terms electrode, electrolyte, electrolysis – the detailed process is not required).
  • Preparation of the hydrogen in the laboratory.
  • Preference of zinc as metal to be used (with reasons).
  • Choice of dilute acids (other than dilute nitric acid).
  • Bosch’s process.
  • Properties and uses of hydrogen.
  • Oxidation and Reduction.

   

  UNIT 8: Water

  • Dissolution of salts in water –it’s meaning and explanation.
  • Universal solvent – meaning.
  • Solutions, suspensions, colloids.
  • Differentiate unsaturated/saturated and supersaturated solutions.
  • Suspensions and colloids.
  • The water of crystallisation.
  • Hydrated and Anhydrous substances, hygroscopic.
  • Reactivity of the metals with cold water, hot water and steam (with the products formed).
  • Hard and soft water and the methods of softening hard water.
  • The disadvantage of using hard water.
  • Removing the hardness of water by boiling it or by treating it with washing soda

   

  UNIT 9: Carbon and its compounds

  • Crystalline and amorphous nature of the allotropes of carbon.

  Allotropes of Carbon – definition and explanation.

  • Uses of diamond, graphite, coke, coal,
  • and soot.
  • Physical properties of Carbon dioxide.
  • Chemical properties of Carbon Dioxide.
  • Laboratory preparation, its properties and uses of carbon dioxide
  • Reaction with lime water.

  Acidic nature.

  • Properties and uses of Carbon monoxide.
  • Emphasis on use as the reducing agent in the extraction of iron.
  • Emphasise the harmful properties of Carbon monoxide when it is inhaled – Asphyxia.

   

• Recomended Audience:

  The audience of this course is students of Grade-8from ICSE Board. All the Chapters are well designed and its coverage as per latest curriculum released by the board. Still Student have complete flexibility to enhance or modify the course coverage during the course of learning process with Teacher. We are expecting that students of Grade-8 should drive their classes with Teacher as per chapters mentioned and also as per syllabus of their school and applicable School district or Board.

• Pre-Requisite Requirement:

  For attending this course, prior knowledge of Grade-7  Chemistry  is required, this course assumes that students have prior experience with all the topics of Chemistry  of Grade-7. This is not an introductory class for absolute beginners on Chemistry  of Grade-7. Participants should already be familiar with the basic learning objective.
